## Question:

A chemist has a solution of {eq}\rm NaOH\ 4\ mol/L {/eq} and wishes to prepare {eq}500\ mL {/eq} of a solution at {eq}\rm 3\ mol/L {/eq}. What volume should it use from the {eq}\rm 4\ mol/L {/eq} solution?

## Dilution of Solutions:

In our Chemistry experiments, we would sometimes need to dilute a stock solution to our desired concentration and volume of a reagent. In diluting solutions, the equation, {eq}\displaystyle M_1V_1 =M_2V_2 {/eq}, would be very helpful, where {eq}\displaystyle M {/eq} is the molarity and {eq}\displaystyle V {/eq} is the volume and the subscripts depict either the stock or the desired solution.
